In other words, Jeff "get" 15% of the total sales.
You would multiple total sales by percent in decimal form.
That would be $2464 × 0.15 = $369.6
Final answer: $369.60
Answer:
(a) 110 mm Hg
(b) 70 mm Hg
(c) 3/4 second
(d) see the attachment
Step-by-step explanation:
(a) The sine function has a maximum value of +1, so the maximum value of p is ...
pmax = 20·(+1) +90 = 20+90 = 110 . . . . . mm Hg
__
(b) The sine function has a minimum value of -1, so the minimum value of p is ...
pmin = 20·(-1) +90 = -20+90 = 70 . . . . . mm Hg
__
(c) The period of the sine function is 2π, so the value of t that makes the argument be 2π will be the period.
8π/3·t = 2π
t = 2π·3/(8π) = 3/4 . . . . . . multiply by the inverse of the coefficient of t
The period of her heartbeat cycle is 3/4 seconds.
__
(d) a graph is attached.

If you distribute, then you get -10x+7.5
Note how -2.5 times 4x = -10x and how -2.5 times -3 = 7.5
The idea is that you multiply the outer term (-2.5) by each term inside
Answer:
x = 5
Step-by-step explanation:
The square mark on one of the angle states that the angle is a right angle, meaning that it is 90°.
If you only include the three angles, 8x - 5, 90°, and 55°, then they are supplementary angles.
Supplementary angles are angles that should add up to 180°.
So the equation is:
8x - 5 + 90 + 55 = 180
Now solve:
8x - 5 + 145 = 180
8x + 140 = 180
8x = 180 - 140
8x = 40
x = 40 ÷ 8
x = 5
